What aspect of the Sims 4 do you enjoy most?

I'm a very gameplay oriented person but, since I think the biggest shortcomings of TS4 are related to gameplay, I picked CAS. I mean, my priorities for downloading fan made content has completely flipped on its' head with this tittle. Whereas in TS2-TS3 I downloaded tons of CC and hardly any mods, this time I'm getting tons of gameplay mods and only very few CC items. Like, sure, I enjoy the gameplay now with mods and spend most of my time there but the fact remains that it required mods for me to truly enjoy it. Therefore I don't think it's very accurate for me to say "gameplay is the best part of TS4".
While there are some clunky things about CAS I think it's VERY robust and I love how you basically have no restrictions (compared to previous games). You can wear any outfit for any category for any gender. It also lets you pick their walk style, decide whether the sim can get pregnant and so on. I also absolutely love how you can have unique body shapes instead of it lamely being restricted to "thin or fat".
